COMPOSITE, BUILDING STRUCTURE.

To all whom 2'15 may canoe-m:

Be itknown that l, PEREZ M. Srawan'r, a; citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an-Im-.-

.pr'ovement inComposite Building Structures, ofwhich the following description, in connection with the accompanying drawings,'is a specification. like letters. onthe drawings representing like parts.

This invention relates to a composite building structure of sheet metal and plastic -material, which isreinforced, and is especially adapted for use in a building as a. Wall or siding. V

The invention has for its object to proyide a superior, light and fireproof wall or siding, as will be described. To this end, I em ploy a metal sheet, composed of asbestos protected metal, in which layers 01'- sheets of fire-proof material such as asbestos are afiixed to the opposite sides of the-metal sheet by asphaltum or like cement. .The.

substantially horizontal members of the clapboard sheet form a series of shelves-for supporting plastic materialsuch as concrete, which may and preferably Willbe reinforced as will be described: These and other features of this invention .Wlll be pointed out in theclaim at the end of this specification.

Figure l is a perspectiveflivith jparts broken away of a Wall embodying this inventionl Fig. 2, a section on'anenlarged scale of the clapboard asbestos protected metal sheet shown in Fig. 1. Fig. 3, a sec .tion on'ithe line 3 3, Fig. 1. Fig. 4-, ajsection on the line 4-4, Fig. 1. Fig. 5, a section on the line 5+5, Fig. 1*, and Fig.6, a; section on the line 6+6, Fig. 5.

Referring to-the drawings, a. represents 1 the clapboard metal sheet, which is -a sheet of asbestos protected mtahinwjhic'li the ,metal sheeta is provided on-its opposite surfaces with layers .7) of asbestosor like fire-J proof material, cemented to the metal sheet;

The clapboard metal sheet a is bent, termed or. shaped to form a plurality of substan Qtially parallel inclined sections.or,;members '50 10 and substantially ;.h oriz 'ontal member's or sections: 12,'= which connect the lower end of one inclined section with the upper endjctthe n'eXtad acentinclined section; The clap-d board sheet'a'imay be secured to vertical sup- 1 5 ports 13, such'as angle irons, by means of l izig a metal: sheet having on onelsurface aboard to the siding. v

It is preferred to make the clapbo'ardsheet f of asbestosprotected metal, as the asbestos zontal supports,-shown as angle-irons 16, by similar bolts 7 .andfclips 1-8. The horiplastic materialQO', such as" plaster,concrete.

Claim:

A composite building structure comprising a metal sheet having a plurality of substantially parallel inclined sections and substantially horizontal. sections, a Waterproofing and insulating cement covering the opposite surfaces of said metal sheet layers of asbestos fabric aflixed to the opposite sur- 20 faces of said metal sheet by said cement, a

material, and a metal reinforcement for said 2 1 plastic material, substantially as described.
